I18N Gallery

[ffooccuuss]

I migrated my site to a new host (installed GS 3.1.2 fresh, then copied data over per the wiki article on migration). Creating galleries was working at the previous host using version 1.9.3.

Now when I click "Add image" in the "Create new gallery" page, the new window that pops up for imagebrowser.php comes up with the error "Oops! Page not found!"

I tried reverting to version 1.9, no luck. Wiped the new host clean and installed GS 3.1.2 fresh, set up password, site name, etc. and installed gallery 1.9.3 fresh. Same "oops, not found" message on the imagebrowser page.

Everything comes back "OK" in Website Health Check - does I18N Gallery require something more from the host? Is there anything I can try to get galleries working on this host?

Thanks in advance!
